Physics and Astronomy Colloquium
A theorist's introduction to attosecond physics
Presented by Dr. Vladislav S. Yakovlev, Center for Nano-Optics (CeNO), Georgia State University
Attosecond physics studies phenomena for which a characteristic time scale is smaller or comparable to a femtosecond (1 fs = 10-15 seconds, 1 attosecond = 1 as = 10-18 seconds). Initiated by technological breakthroughs in laser science, this field of research has progressed rapidly over the last decade, inspiring numerous theoretical investigations. In my presentation, I will review the basics of attosecond physics, as well as several highlights from my work at the Laboratory for Attosecond Physics (LAP). My talk will cover three main topics: (i) generation of high-order harmonics in gases, which is the primary source of attosecond light pulses, (ii) theoretical analysis of attosecond measurements, where the main challenge is retrieving valuable information from available data, and (iii) strong-field-driven electron motion in solids, which is a relatively new but very promising research direction.
